AI Technical Summary

Technical Problem

Frameless door side sealing strips are prone to shrinkage or slippage under external force or temperature changes, resulting in a decrease in sealing effect.

Method used

A side sealing structure is designed, including a sealing strip body and a sealing strip corner. The sealing strip corner has a limiting part, which abuts against the cut edge of the side bright strip to achieve axial limiting, and engages with the side bright strip through a snap-fit ​​channel to form a double limiting, ensuring the stability of the sealing strip.

Benefits of technology

It improves the stability and sealing effect of the sealing structure, solves the problems of easy displacement and sealing failure of the sealing strip, and improves the NVH performance and ride comfort of the vehicle.

Claims

1. A side seal structure, characterized by, include: Sealing strip body (100); A sealing strip corner (200) is connected to one side of the sealing strip body (100). The sealing strip corner (200) has a first slot (210) and includes a limiting part (220) which is disposed in the first slot (210). The sealing strip body (100) is used to connect with the side bright strip (300), the first slot (210) is used to accommodate part of the side bright strip (300), and the limiting part (220) is used to abut against the side bright strip (300).

2. The side seal structure of claim 1, wherein The sealing strip body (100) has a second slot (190), which communicates with the first slot (210) and forms a snap-fit ​​channel (400); The side bright strip (300) includes a first snap-fit ​​part (310), which is disposed in the snap-fit ​​channel (400) and snaps with the sealing strip body (100) and the sealing strip corner (200) respectively. The side of the first snap-fit ​​part (310) facing the sealing strip corner (200) abuts against the limiting part (220).

3. The side seal structure of claim 2, wherein The sealing strip body (100) includes a main body (110) and a first protrusion (120). The first protrusion (120) protrudes from one side of the main body (110) and is disposed toward the side bright strip (300). The main body (110) and one side of the first protrusion (120) form the second slot (190).

4. The side seal structure of claim 3, wherein The sealing strip body (100) further includes a second protrusion (130), which is connected to the side of the main body (110) away from the first protrusion (120); The second protrusion (130) and the main body (110) form a third slot (132) and a fourth slot (133). The opening of the third slot (132) faces the side bright strip (300), and the opening of the fourth slot (133) faces the opposite direction to the opening of the third slot (132).

5. The side seal structure of claim 4, wherein The sealing strip body (100) has a cavity (131) that extends through the second protrusion (130) along the extension direction of the main body (110).

6. The side seal structure of claim 4, wherein The sealing strip body (100) further includes a first lip (140), which is disposed at one end of the main body (110) near the second protrusion (130), and the end of the first lip (140) away from the main body (110) extends toward the interior of the sealing strip body (100).

7. The side seal structure of claim 6, wherein The sealing strip body (100) further includes a second lip (150), which is disposed at one end of the main body (110) near the first protrusion (120) and opposite to the first lip (140). The end of the second lip (150) away from the main body (110) extends toward the interior of the sealing strip body (100).

8. The side seal structure of claim 7, wherein The sealing strip body (100) also includes a third lip (160), which is connected to the interior of the main body (110), and the end of the third lip (160) away from the main body (110) extends toward the side bright strip (300).

9. The side seal structure of claim 8, wherein The sealing strip body (100) also includes a plurality of third protrusions (170) arranged in sequence. The third protrusions (170) are disposed on the side of the main body (110) away from the side bright strip (300), and the end of the third lip (160) away from the main body (110) faces the third protrusions (170).
